Over the last few days, the Debian security team has announced fixes to several XMPP server daemons to address the so-called "billion laughs" attack: http://lists.debian.org/debian-security-announce/2011/msg00118.html http://lists.debian.org/debian-security-announce/2011/msg00119.html http://lists.debian.org/debian-security-announce/2011/msg00120.html This attack is not limited to those server daemons, and in fact applies more generally to any XML-based applications. Other XMPP software projects (servers, clients, and libraries) might also vulnerable, and developers are encouraged to review their code.
